Periodic Maintenance
WARNING: Accidental Starts!
ȱǯȱȱȱȱȱȱ¢ȱȱǯȱBefore working on the engine or equipment,
disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) baery cable from baery.
Maintenance Schedule
Normal maintenance, replacement or repair of emission control devices and systems may be performed by any
repair establishment or individual; however, warranty repairs must be performed by a Kohler authorized
service center.
Storage
If the engine will be out of service for two months or
more, use the following storage procedure:
1. Clean the exterior surfaces of the engine.
2. Change the oil and oil filter while the engine is
still warm from operation. See Change Oil and
Oil Filter in Section 6.
3. The fuel system must be completely emptied,
or the gasoline must be treated with a stabilizer
to prevent deterioration. If you choose to
use a stabilizer, follow the manufacturer’s
recommendations, and add the correct amount
for the capacity of the fuel system. Fill the fuel
tank with clean, fresh gasoline. Run the engine
for 2-3 minutes to get stabilized fuel into the
carburetor.
To empty the system, run the engine until the
tank and system are empty.
4. Due to the deep recess around the spark plug,
blow out the cavity with compressed air. Remove
the spark plug. The spark plug is most accessible
when the blower housing is removed for
cleaning.
Add one tablespoon of engine oil into the spark
plug hole. Install the plug, but do not connect
the plug lead. Crank the engine two or three
revolutions. Connect the plug lead.
5. Reinstall the blower housing, if removed
previously, and torque the blower housing screws
to 7.5 N·m (65 in. lb.).
6. Store the engine in a clean, dry place.
¹Perform these maintenance procedures more frequently under extremely dusty, dirty conditions.
²Have a Kohler Engine Service Dealer perform this service.
